Do deer like antenna wires?

Our garden is frequently visited by roe deer. They like to trek along the little brook that runs at the edge of the garden. Usually that has few consequences.

But this weekend as I was about to contact stations during the CQ160CW contest, I noticed that nobody could hear me. I heard many stations, but nobody seemed to hear my signal.

The Imagined Conflict

I have a new independent blog named after my book "The imagined conflict". The book was published in November 2025 and is a revised translation of a book first published in Norwegian in 2021 and in a second printing in 2022. 

The new blog may be reached by clicking here.

Science with Overtones

Science with Overtones:
21 Natural Scientists and Their Belief in God.

Scientists with a belief in God have played a central role in the development of science for more than four hundred years. Some might think that belief in a creator God and the practice of science must have been a source of conflict, but the stories of the scientists tell a completely different story. They had a divine perspective on science, and it made their work better, not worse. Be inspired by 21 of the world's most important scientists!

The book has two authors. First, Professor Sverre Holm presents the scientist's life's work and beliefs, then Sven Aasmundtveit reflects on what this can mean for us today.

The book is in Norwegian and in sale from October 30.

My Ruyage UV58Plus changed into a completely new radio

New look (M70CM 3.2/P2.0)

I bought the Ruyage UV58Plus (also called Radtel 890) in August 2023. I liked its display as it would show both the frequency and the name of the station at the same time, and many Chinese handheld transceivers don't do that.

On the other hand, its scanning function wasn't very good, so I was a little disappointed. It sensitivity was also poorer than that of my Baofeng UV-5RE. But at a cost of 34 Euros + VAT, it was OK.

But that was before I found out that its firmware could be updated. I had originally V1.33, 2023-02-10. The images below show it with V1.35 2023-10-20.

The surprising faith of scientists

"The surprising faith of scientists" is the tentative title of a book manuscript just submitted. 

The book stems from a discovery I made some time after I had completed my university studies where I had studied theories named after the likes of Pascal, Ampere, Faraday, Maxwell, and Kelvin. The surprising thing was that all of these were devout Christians. It would turn out that there were many more of them.

The magic of adaptive filters in amateur radio

Examples of a speech signal (top),
a sinusoidal, and noise (bottom)

Radio amateurs have been using adaptive noise reduction and adaptive notch filters for decades. They came with the advent of audio digital signal processing. 

Few however, understand how different they are from ordinary frequency selective filters and for many they appear to do something magic, very different from ordinary filters.

QMX+ mechanical improvements

My QMX+ has some minor mechanical improvements:

1. Slimmer knobs. I decided to replace the knobs as I often touched the bottom one while adjusting the top one and vice versa. The slimmer knobs solved that. I found knobs on AliExpress with the same looks, only a smaller diameter as the image shows. Unfortunately they don't have screws, so they aren't so well attached as the original ones.
2. Folding laptop feet which I first saw on the AE5X blog.
